CORPORATION OF PENNSYLVANIA SPOOL FOR. YARNS OR THREADS Application filed September 23, 1930. Serial No. 488,918.

My invention relates to the construction of spools which are designed for use in the manufacture of yarns and threads, natural or artificial, and the object of my invention is to provide a construction of spool which will not be liable to break the yarn or thread while it is being drawn off the spool in twisting, spinnin knitting or the like. This object ll secure y making the spool in two parts each of which carries its own flange, one part being a tubular body upon which the thread or yarn is wound in the first instance and the other being a core with expansible fricti'onal means to hold it in the tubular part when desired, but this core with its flange being removable and replaceable by a separate flanged piece when the yarn or thread is to be drawn oil the spool.

In the accompanylng drawing 2 Fig. 1 is a longitudinal section through the tubular part of the spool, but with the expansible core in place; i

Fig. 2 is a transverse section on the line 2-2, Fig. 1;

Fig. 3 is a side view of the expansible core removed;

-Fig. 4 is a sectional view of a form of flange, to be substituted for the removed exas indicated by dotted lines The part of the spool on which the thread or yarn is wound consists of a-tubular part A, which conveniently may be of wood, and having secured to one end as by screws, or other suitable means, a flange B, preferably of metal.

Combined with this tubular part is a frictional core C, preferably of metal and having secured to one end by any suitable means a ange C. For lightness this core may be made of aluminum or other light metal in the form of a longitudinal central spindle c with spaced end and central flanges c, c and c. There may be secured to the end flanges journals j, to permit the spool to be mounted in bearings horizontally in winding.

To illustrate the purpose, use and advantage of my improvement, I will cite by way of example its use in the manufacture of rayon thread or yearn. The spool is first mounted as shown in Figs. 1 and 2, with the expansible core in place in the tubular part of the spool, which is then mounted by the journals 7' of the core part, horizontally, in suitable bearings in the twisting and windin machine, and the yarn or thread is twists and wound on the spool on a twisting frame. Then the spool with the thread or yarn on it is subjected to a steaming process to set the twist. Thereafter the spool has to be set vertically on a spindle or other support in Fig. 5 to draw the thread or yarn ofl it onto suitable cops, bobbins, etc., or in knitting.

In the handling of these spools, particularly in the steaming operation and afterwards, they are apt to be subjected to more or less rough treatment, with the result commonly that the edges of nicked, dented and roughened, and consequently in drawing the yarn or thread 0d the the flanges become substitute flange not being subjected to any rough usage, its flange will remain smooth, so that when the spool is mounted vertically,

. or damaged.

fit therein,

. in any machine in which the yarn or thread is to be drawn off over the edge of this smooth flange, the yarn or thread will not be broken This substitute flange 1) may be of wood, metal or composition of wood or composition of metal. to load it with lead, as indicated at d in Fig. 4, to give it suflicient weight.

I claim as my invention:

1. A spool for yarn or thread, consisting of two parts, one a tubular part carrying a winding retaining flange at one end in combination with a removable core to fit therein, said core having a corresponding flange at the other end, journals at both ends, and yielding means retaining said core in place.

2. A spool for yarn or thread, consisting of two parts, one a tubular part carrying a winding retaining flange at one end in combination with a removable frictional core to said core having a corresponding flange at the other end,j ournals at both ends, and yielding means retaining said core in position.

3. A spool for yarn or thread, consisting of a tubular body with a winding retaining flange at one end in combination with a removable core having journals at both ends, a corresponding flange at one end and spaced yielding means for retaining said core in position, the tubular body being adapted to receive a substitute short core with flange on removal of the journaled core.

4. A spool for yarn or thread comprising a tubular body having a winding retaining flange at one end and a removable core having journals at each end thereof and a corresponding flange at one end thereof, annular flanges spaced along the length of said core and fitting said body and resilient means extending between said annular flanges for retaining said core in said body.

5. A spoolfor yarn or thread comprising a tubular body having a winding retaining flange at one end and a removable core hav ing a spindle provided with journals at each end and a yarn retaining flange at one end, spaced flanges on said spindle fitting within said body and yielding means carried by said spaced flanges for retaining said core in said body.

In testimony whereof I have signed my name to this specification. I

HENRY JOHNSON.
